Linux下mysql新建账号及权限设置方法
Linux下mysql新建账号及权限设置方法,其实linux与windows下的设置方法一样的,都是命令行操作
1、权限赋予说明:mysql部署在服务器A上,内网上主机B通过客户端工具连接服务器A以进行数据库操作,需要服务器A赋予主机B操作mysql的权限
1.1 在服务器A上进入mysql,假设在服务器A上mysql的账户是root:
代码如下:
mysql - u root -p
然后回车键入密码!
1.2 赋予主机B操作数据库的权限
代码如下:
mysql> grant usage on *.* to username@192.168.0.1 identified by 'password';
说明:赋予username@192.168.0.1 使用所有数据库的权限,在主机192.168.0.1上使用username账户登录,密码为:password
代码如下:
mysql> grant all privileges on newdb.* to username@192.168.0.1;
说明:赋予username@192.168.0.1 操作数据库newdb的最高权限,在主机192.168.0.1上使用username账户登录,无密码
举例:
代码如下:
mysql> grant all privileges on *.* to root@192.168.0.1 identified by '123456' ;
说明:赋予root@192.168.0.1 使用所有数据库的权限,在主机192.168.0.1上使用root账户登录,密码为:123456
2、移除账号
代码如下:
mysql> drop user root@192.168.0.1;
说明:移除账户root,这样,主机192.168.0.1就不再可以使用root用户操作服务器A上的数据库
